Description Andrea Somaini 2020-04-28 18:50:19 UTC
I have this GPU installed on my system: https://www.powercolor.com/product?id=1493084304

The problem is that the power usage while using Linux and just looking at the desktop is much higher than on Windows, in particular:

~7,2 Watt Windows 10
~31,2 Watt Linux (Xorg, Wayland, tty only etc)

It is more than 4 times as much power!

Indeed, after a while doing light web browsing, the temperatures are different in the 2 systems with the GPU fans turned off, in particular:

~37.0°C on Windows 10
Between 43.0°C and 50.0°C on Linux
